AIR AND SMOKE SPREADER AND DISTBIBUTER FOR SMOKE-HOUSES.

SPECIFICATION forming part of Letters Patent No. 355,706, dated January11, 1887.

Application filed May 14, 1886. Serial No. 202,140.

(No model.)

To all whom it may concern.-

Be it known that I, NICHOLAS MURPHY, a citizen of the United States,residing at the city of Chicago, in the county of Cook and State ofIllinois, have invented certain new and dry houses in which meats aredried, or

dried and smoked, by the application of hot air or smoke from a furnaceor smoke-generator situated in another room or building from saidsmoking and drying room'and conveyed to said room by flues.

The object of my invention is to obtain a spreader and distributor bywhich thewhole or any desired amount of the heat or smoke coming fromsaid furnace or generator may be distributed to and toward any part ofthe smoke and drying room.

I have illustrated myinvention by the drawings accompanying thisspecification and forming a part hereof, in Which Figure 1 is alongitudinal sectional view of my improved air and smoke spreader anddistributer. Fig. 2 isa'plan view of my improved air and smoke spreaderand distributor from line 2 of Fig. 1, viewed in the direction of thearrow. Fig. 3 is a plan view on line 3 of Fig. -1, viewed in thedirection of the arrow.

Like letters refer to like parts. throughout.

the several views.

A is the pipe or flue from the furnace or generator to the smoking anddrying room.

B is a cone-shaped portion of my invention extending from flueA to andsupporting 1101- low cap and spreader B.

B is a hollow or dead-air cap and spreader.

- b is a flange on the inner surface of cone B.

b is a bolt and .nut securing spreader B to cone B.

Gis a metal flange on the outer surface of cone B. Flange O rests on ornear to the upper surface of the floor of the smoking and drying room.Ihe diameter of thehole in said floor through which the fine and conepass into said drying and. smoking chamber is larger than the diameterof said flue and cone, and slide 0 is placed in said flange G for theadjustable admission of air into the smoking .and drying roomindependent of and without passing through my improved air and smokespreader and distributer.

D is a wire screen or perforated plate resting on flange b.

E is a casting or spider'secured to the upper end of cone B, withflanges e e thereon.

Screen Dis placed in my air and smoke 6o spreader and distributor when,from the character of the fuel used in producing smoke or heat,unconsumed portions thereof or cinders are liable to be carried into thesmoking and drying room along with said smoke or heat.

Dead-air cap and spreader B is hollow, as illustrated in Fig. 1, and thepurpose thereof is to prevent, .to a large extent, the distribu- .tionof heat by radiation from the upper surface thereof.

The smoke or heated air entering the smoking and drying chamber throughmy improved air and smoke spreader and distributor passes between theouter surface of dead-air cap B I and the inner surface of cone B, asillustrated 7 in Fig. 1, and the amount and direction thereof iscontrolled by dampers F F.-

If it be desired to admit air into the smoking and drying chamberindependent of the smoke and air spreader and distributor, the same maybe readilydone by damper 0 in flange O. P

I do not, however, consider slide 0 an essential part of my invention.

Having thus described my invention, its 8 5 construction and manner ofoperation, what I claim,and desire to secure by Letters Patent,

1. In an iii and smoke spreader and distributer for smoke-houses, thecombination of a cone having a dead-air chamber and spreader in theupper portion thereof, and dampers adjustably placed around saidair-spreader and upon the upper surface of said cone, all substantiallyas described, and for the purpose 5 set forth.

2. In an air and smoke spreader and distributer for smoke-houses, thecombination of dead-air cap or chamber B, and adjustable dampers F F,all substantially as described, 10 and for the purpose set forth.
